ROLLING-MILL BEARINGS.-

Application filed January 24, 1928. Serial No. 249,075.

This invention has reference to new and useful improvements in bearings0r brasses for rolling mill rolls and particularly to that i type ofrolls employed in mills for rolling 5 sheets, tin plate and the like.

The invention has for its principal object to improve the manner ofmaintaining the upper and lower hearings or brasses against endwise aswell as sidewise movements.

A stillfurther object is to provide the top and bottom brasses for therolls with means to prevent endwise as well as sidewise move ment ofthese brasses.

The foregoing objects are obtained by means ofwhich the weight of thematerials are reduced, the cost of mill practice is lessened and thepractice of changing the several bi-asses made more easy and expedient.

That the invention may be more fully understood, reference is had to theaccompanying drawings, forming part of this description, illustratingpreferred embodiments of the invention, in which Fig. 1 is a. verticalsectional view through a rolling mill embodying the invention, saidsection being taken through the necks of the rolls and looking towardthe adjacent hous- Fig. 2 is a vertical sectional view, as'the samewould appear if taken on the line 2-2 Fig. 1, looking in the directionof the arrows;

Fig. 3 is a detail in plan, partly in section, showing a bearing orbrass, such as would be used for the top or bottom roll;

Fig. 4 is a perspective view of the brass shown in Fig. 3', and

Fig. 5 is a view somewhat similar to Fig. 3, but showing a modified formof top or bottom brass.

any usual and well known construction, and

the rolls 2 may also be of any usual and well known construction,provided with necks 3 and fillets 4 at the intersection of the neck androll.

The upper and lower hearings or brasses are designated respectively, 5and 6, the former adapted to be seated in a pocket or recess 7 in theoverlying rider 8 and the latter adapted to be seated in a pocket orrecess 9 formed in the housing 1. These brasses 5 and 6 are preferablyrectangular in form, one end of each being abruptly squared, whereastheir opposite ends are beveled or inclined, as at 10, and such beveledends of these brasses are disposed next adjacent 'the fillet portions ofthe rolls but spaced therefrom, see Fig. 2, to provide the pocket-likespaces 11 in which to place a heavy grease lubricant, if desired. Thebrasses are formed with concave surfaces 12 to receive complementarysurfaces of the roll necks and their sides are shouldered, as at 13throughout their length, which terminate at the opposite corners of thebrasses in off-set or laterally disposed lugs 14. The pocket or shapedwalls to receive the angularly shaped sides of the top and bottombrasses 5 and 6. This arrangement is best seen in Fig. 3, where thehousing 1 is formed or provided, at opposite sides with sets ofoff-sets, shoulders or recesses 15 to receive the lugs 14. Soassemble'd, it will be obvious that the coacting lugs 14 and shoulders15 at the opposite ends of the brasses 5 and 6 will prevent endwise aswell as sidewise movement of such brasses. It may be desirable to limitor stop endwise movement of the brasses 5 and 6, in one direction, bythe use of coacting lugs 14 and shoulders 15, as has been described, andto limit or stop endwise movement of the bi-asses 5 and 6, in theopposite direction by tapering or making the shouldered sides 13 of thebrasses wedge-shape, as at 16, see Fig. 5, to coact with. similarlyshaped walls 17 in the pocket or recess 7 of the rider 8 and in thepocket or recess 9 in the housing 1.,

What we claim is In combination with a supporting member having awedge-shaped recess formed on each .of its sides and at its end of leastwidth with lateral cut-outs, a brass of wedge-shape conformably fittedin said recess, and lateral lugs on the sides and at the end of thebrass THOMAS H.
